When building for jetson-agx-orin-devkit and following the instructions indicated on the page:

I see the following error:

WARNING: optee-os-tadevkit-3.22.0-l4t-r36.3.0-r0 do_fetch: Checksum failure encountered with download of https://developer.download.nvidia.com/embedded/L4T/r36_Release_v3.0/sources/public_sources.tbz2;downloadfilename=Jetson-public_sources-36.3.0.tbz2 - will attempt other sources if available

File: '/home/njacobson/demo.mender/meta-mender-community/my-build/build/downloads/Jetson-public_sources-36.3.0.tbz2.tmp' has sha256 checksum '190f499f5cff26f62a911d25a8e4c384db613a1887cbce17bcbe5810be0f36c9' when 'e94dbe0025ae313eeb603061697afed77b9641d2a06df022888574562dd1f6c5' was expected
If this change is expected (e.g. you have upgraded to a new version without updating the checksums) then you can use these lines within the recipe:
SRC_URI[sha256sum] = "190f499f5cff26f62a911d25a8e4c384db613a1887cbce17bcbe5810be0f36c9"
Otherwise you should retry the download and/or check with upstream to determine if the file has become corrupted or otherwise unexpectedly modified.

Changing the expected checksum in the manner indicated - just to see if that helps - does not resolve the issue. Has anyone else seen and resolved this issue?

The answer is that since the kas yaml file can only pull a branch using a specific commit tag, if the branch is updated elsewhere and that commit hash is no longer compatible with the latest version of that branch - you are in deep doo-doo. That appears to be what happened on the scarthgap branch. I updated the commit tags in the jetson-agx-orin-devkit.yml locally to the latest scarthgap hashes (git show-ref scarthgap) and now the build works. I did not push my change because I feel like too much of an amateur to do that.
